FOOTWEAR.

SPECIFICATION forming part of Letters Patent No. 650,557, dated May 29, 1900.

Application filed September 21, 1899- Serial 111- 731,183. (No model.)

To all 2071/0122, it may concern.-

Be it known that I, EDWARD J. I'IARTMAN, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Footwear, of which the following is specification.

My invention relates to fsetweaznin the nature of boots and shoes, and has for its object the providing of a separable heel and, if desired, a separable sole, so that when the same are worn' they may be replaced by a new heel or sole, or,if desired,the boot or shoe, by means of my improved device, may

be provided with interchangeable heels and soles, so that the same boot or shoe may be used for various purposes-as, for instance, street-wcar-and so arranged that the heel or sole thereon may be interchangeable with a heel or sole provided, for instance, with spikes and adapted to housed in hunting or outdoor exercise or sports. 1

My invention consists in the parts and in the construction, arrangement, and combinations of partshereinafter more fully described and claimed.

In the drawings, Figure 1 is a bottom view of an article of footwear with the outer heel and sole removed and provided with a part of my improved devices. Fig. 2 is a plan view of the detachable heel nd F g. 3 plan View of the detachable so Fig. 4' is an irregular section of my improved device, showing the parts joined, taken on a line corresponding to the line a; a: of Fig. 1. Fig. 5 is a corresponding view of my improved device as applied to the sole of the shoe, showing the parts joined, taken on a line corresponding to the line 3 y of Fig. 1. Fig. 6 is a section of my improved device on a line corresponding to the line .2 z of Fig. 1, showing the parts in locked relation. Fig. 7 represents the locking-plate with its cap and plate, showing the parts detached. Fig.8 is side elevation of thelower heel-section plate. Fig. 9 represents the locking-plate. Fig. 10 is a side elevation of the locking-key, and Fig. 11 a side elevation of the plug for the opening to the inside of the shoe attached to the inner lining of the latter.

In my improved device I prefer to divide the heel and the sole into two parts or seetions-an upper or permanent sectionand a lower or removable section to which I attach the respective parts of my improved device; but it is obvious that the parts attached to the upper sections of the heel and sole may, if desired, be attached to the insole of a boot or shoe.

A represents the upper section of the sole;

wear, and O the upper heel-section, D the lower heel-section, and E the lower sole-section, of the article of footwear. I provide the bottom of the upper heel-section with a plate 1, slightly smaller than the heel-section and which may be .attached thereto by means of pegs 2. The upper heel-section is recessed, as at 3, to a depth corresponding substantially to the thickness of the plate 1 and also to receive the cap hereinafter mentioned. The plate 1 is preferably provided with scallops 4, so as to increase the body of the leather 5 between the plate and outer edge of the upper heel-section. The plate 1 has apertures 6, through which projections 7 of a cap 8 are adapted to take and be bent and flattened at the other side of the plate, as shown at 9, to retain the cap in place. In the cavity of the cap a locking-plate 1O isplaced. This locking-plate is preferably in the form shown in Fig. 9 and is provided at its edge with recesses 11, forming locking-faces 35, for the purpose hereinafter explained. To one side of the recesses the edge of the lockingplate is formed cam-shaped, as at 12. The plate 1 is also provided with apertures or eyes 13, the heel-section under the eyes being hollowed, as shown at 14. The eyes preferably slant upwardly through the plate from the rear toward the front of the shoe. The lower or removable heel-section is provided with a plate 21, secured thereto by pegs 22, the lower heel-section being recessed, as at 24, to a sufiicient thickness to receive the plate, with its upper surface substantially flush with the upper surface of the lower heelsection. It may also be provided with scallops 25, corresponding to the scallops 4: in the plate 1 in such manner that the scallops may be above one another when the parts are connected and the leather portions of the two '13, the shank or body of an article of foot-- sections meet. For this purpose the leather edges beyond the plates may project slightly above the plates. The plate 21 is provided with hooks 26, which take into the eyes 13 in the plate 1. The hooks 26 ar nreferabl" bent in such form that their lower faces" 'slan't upwardly to correspond to the slant of the eye-faces and form an incline or wedge to help drive the lower heel-section home when being fastened. The hooks 26 are preferably provided with inclined side faces 27 at their outer edges, which are adapted to take against the corresponding outer edges 15 of the eyes 13 and lead the lower heel-section to proper transverse position with relation to the upper heel-section when the lower heelsection is broughthome to proper position, so

that the sides of the heel-sections may beflush. The plate 21 is also provided with shouldered projections 28, adapted to take through apertures 16 in the plate 1, the recesses 11 in the locking-plate 10, and apertures 17 in the cap 8.

In attaching a heel the hooks 26 are first brought into engagement with the apertures orv eyes 13 on the plate 1. The shouldered projections 28 are then brought to pass into and through the apertures 16, recesses 1 1 and apertures 17, just mentioned. Theloc'king-plate is provided with a square or other suitably-shaped opening or seats 29 toreceive a correspondingly-shaped end 30 of a key 31. l The looking-plate is turned by means of the key, bringing the unrecessed portion of the locking-plate under the shoulders 32 of the projections 28. I have shown the projections 28 punched out of the body of the plate 21, leaving openings 23 therein. The books 26 may besimilarly formed.

In order to bring the parts home properly when fastening the same, the locking-faces 35 are preferably inclined next to the recesses 11, forming inclined locking-faces 36, which draw the shoulders 32 inwardly while the inclined faces are passing thereunder. The cam-faces 12 on the locking-plate lead the shouldered projections to proper position. The rear faces of the projections 28 are also slightly inclined, as shown at 27. These rear faces impinge against the rear edges of the apertures 16 in the plate 1 and force the lower heel-section forward s1 as to bind the front wedge-shaped faces of the hooks 2 against the forward wedge-shaped faces of the apertures or eyes 13, causing the lower heel-section to be firmly held and locked by means of the shoulders 32 of the projections 28 climbing on the inclined faces 36 of the locking-plate 10, thereby drawing the lower heel-section inward and causing the rearinclined faces 27 to impinge against the rear edges of the apertures 16 in the plate 1 and throw the lower heel-section forward, causing the forward wedge-shaped faces of the hooks 26 to climb on the forward wedge-shaped faces of the apertures oreyes 13.

If desired, a strip of rubber 41 or other material impervious to wateror moisture may be placed surrounding the outer edges of the plates 1 or 21, thereby aiding in preventing access of water or moisture to the operating parts of my device and to the interior of the shoe. The key 31 is inserted into the looking plate from the interior of the shoe through an opening 42 in the insole and an opening 43 in the cap, leaving no opening in my improved device from the outside of the shoe for the admission of water or moisture to the working parts or to the interior of the shoe. The opening 42 is in practice very small and consequently occasions no inconvenience or injury to the wearer; but, if desired, the opening may be closed by a suitable plug of leather or other substance 44, attached tothe lining 45 of the article of footwear. The plug may extend through the openings 42, 43, and 2S) and an opening 46, which may be made the end 30 of the key 31 to pass therethrough to give the latter a better hold on the locking-plate.

The cap 8 is provided with an opening 46, into which a laminated edge or projection 47 on the locking-plate may take, the projection being adapted to strike the edge 48 of the opening 46 when the locking-plate has been turned to bring the parts home properly to locked position. If it is desired to remove the heel, the locking-plate is turned to bring the projection 47 in position to strike the edge 49 of the opening 46, when the recesses 11 will register with the apertures 16 and 17 and allow the removal of the heel. The key 31 may be provided with a flattened end 33, adapted to be inserted between the heel-seetions to assist in a separation of the parts.

I have thus far described my device as applied priucipall y to the heel portion of a shoe. The sole may also be detachably secured in the same way by corresponding parts, with the exception that I prefer, on account of the increased length of the sole, to increase the number of hooks 26 on the plate 21, and I also find it more convenient to reverse the direction of projection of the hooks. It will be seen that the hooks 26 on the heel-plate 1 extend toward the front or too portion of the shoe. I prefer to allow the hooks 26 on the sole portion of the shoe to project rearwardly toward the heel. I also prefer in the detachable sole to provide two of the locking-plates 10 and their corresponding parts, one at each in the plate 1 to allow side of the shoe, but of relatively-smaller dimensions than the locking-plate for the heel and preferably also provided with but one of the recesses 11. The plate 1 for the sole has also but one aperture 16 and the plate 21 for the sole but one shouldered projection 28 for each of the locking-plates 10. The shouldered projections 28 for the sole also preferably have their shoulders 32 extending toward the toe, and a little play may also be allowed between the rear edge of the shouldered projections and the rear edge of the apertures 16, because the direction of projection of the hooks being reversed the locking action of the locking-plate will depend more on the forcing of the lower sole-section backward by the action of the cams 12 against the forward face of the shouldered projection 28 rather than the wedging action of the rear inclined face 27 against the rear face of the apertures 16, as is the case in the h ck; action.

The reason I prefer tt" ailow the hooks 26 on the lower sole-section to project rearwardly is that when so constructed more pliability is given to the sole. A strip of rubber or other material 41 impervious to water or moisture may also be provided to surround the edge of the plate 1 or 21 for the sole. It is obvious that changes may be made in the construction I have preferred to show without departing from the spirit of my invention.
